Cleaner/red shrimps

[PatW]

I have scarlet cleaner shrimp. I have three in a three hundred gallon tank. They nearly always hang out together. I have not seen any kind of hostile interactions with them. I feed my anemones mysis shrimp. It is like a dinner bell. The shrimp come running. I have a plexiglass glass rod and play whack a mole with the shrimp to give the anemones a chance to devour their meal. The shrimp are amazingly persistent. They also use cover to approach the anemones and try to burst from cover when the coast is clear. So far, they have not used team work. Three shrimp is enough. Any more and I would be overwhelmed.
